PR205 is a new programmable relay with graphic display and Ethernet. The device combines an optimal configuration of analog and discrete inputs/outputs for controlling ventilation, heating, air-conditioning systems, etc. The number of inputs/outputs can be increased by using the expansion modules PRM.
Graphical color screen allows to create convenient and clear user interfaces, which greatly simplifies the configuration and perception of information.
Ethernet interface allows to integrate the device into distributed systems, to increase the number of inputs/outputs with the help of Mx210 I/O modules, to realize remote control and management of equipment with the help of akYtec cloud service. The PR205 includes modifications with 2 RS-485 interfaces on board for data transmission to the upper level and control of other elements of the system.
The PR205 algorithm is built by the user in the free ALP programming environment. This allows to create unique user algorithms and take into account all peculiarities of the system.
